The BMW F12 M6’s S63 4.4L twin-turbo V8 delivers exceptional performance, but its factory exhaust doesn’t fully capture the car’s aggressive potential. The Valvetronic Designs Valved Exhaust System transforms the M6 into a dual-personality machine—capable of refined, luxury cruising or spine-tingling aggression at the touch of a button.
Building on the success of our F10 M5 and F06 M6 systems, this exhaust connects to OEM or aftermarket free-flow downpipes and is engineered for perfect fitment, improved flow, and a signature sound that defines the Valvetronic experience.
Vacuum-Operated Valves: Switch seamlessly between quiet, stock-like operation and a deep, aggressive tone.
High-Flow 3.0" Design: Reduces back pressure and improves scavenging for gains in horsepower, torque, and throttle response.
Material Options: Choose T304 stainless steel for durability or Grade 5 titanium for maximum weight savings and performance.
Valves Closed: Subtle and refined for comfortable city driving or highway cruising.
Valves Open: Bold, commanding tone with pronounced turbo spool and overrun character.
Controller Included: Plugs into the factory harness for reliable, factory-like operation.
Material: T304 stainless steel or Grade 5 titanium.
Weight Savings vs. OEM: –24.8 lb (Stainless) / –51.7 lb (Titanium).
Craftsmanship: Precision TIG welds, fully mandrel-bent tubing, and meticulous finishing.
Tips: Premium finishes available to complement the M6’s styling.

Instructions are included for most parts that require any sort of knowledge to install.
Here's what to do if your parts come WITHOUT instructions:
1. Some parts are genuinely common sense on how they get installed
2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video
3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer
4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed
ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.
Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way
If the part was NOT installed, we accept returns within 14 days of delivery.
If the part WAS installed (or attempted installation), we cannot accept a return.
All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.
YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.
NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.
